Matthew Poole and continuators on Psalms 101:5

5 Whoso privily slandereth his neighbour , him will I cut off: him that hath an high look, and a proud heart , will not I suffer.

Such as by secret and false informations and accusations of others seek to gain my favour and to advance themselves by the ruine of others; which are the common pests of Courts and Kingdoms;

These he mentions, because Pride is the common Plague of Courts, and the Fountain of many enormities in Courtiers; it makes them imperious and insolent towards the poor oppressed Subjects that resort to them for relief; it inclines them to those counsels and courses not which are best for the publick good, but which are most for their own honour and advantage, it makes them oppressive and injurious to others that they may have wherewith to satisfy their own lusts.
